COOLING LARGE VARIABLE FREQUENCY DRIVESThe heat contribution by the converter and inverter sections is approximately 75% of the VFD system heat loss. Typically the VFD system itself is 96 97% efficient. The input isolation transformer is typically 98 99% efficient. VFDs that permit component splitting may offer more packaging and COOLING alternatives for example, being able to locate the input transformer separately (or outdoors) from the COOLING In performing its critical operation, a well-selected VFD COOLING system provides three major functions: 1.

Comparative Selection Points of Air-Cooled versus Liquid-Cooled VFDs In every VFD application, the goal is to minimize initial cost, including installation, and to maximize process payback and energy savings. Knowing the environment in which the VFD will be located, motor power requirements, and the type of load to be driven
